Advanced hydrogen turbine (AHT): The AHT replaces the state-of-the-art F-class turbine (F-class is currently used at Tampa, Wabash River, and is depicted in the baseline IGCC in Figure 2).

The impact of each technology on both process performance and cost were evaluated, and by way of summary the following technological advances and their benefits are expected 1: An IGCC cycle including carbon capture that incorporates these advanced technologies is depicted in Figure 3. Cumulatively, the technology advances targeted both more efficient production of electric power with significant reduction in the cost of electricity (COE). NETL’s Support in Advancement of IGCC TechnologyĭOE’s R&D program has helped develop multiple technologies to improve and increase efficiency of conventional IGCC technology discussed above. CO 2 capture and sequestration (CCS) significantly impacts the overall IGCC efficiency, and the effects are addressed in the discussion Pre-Combustion CO 2 Capture for Gasification Application. The flow scheme of Figure 2 represents a typical process arrangement of a near-term commercial IGCC design without CO 2 capture. Figure 2 : IGCC Block Flow DiagramĪ more detailed process description of each of the processing units within an IGCC complex is presented in the discussion on IGCC process system sections. Oxygen-depleted nitrogen from the EP ASU is compressed back to the GT as diluents for nitrogen oxide (NOx) control, and to maintain mass flow through the GT. Many IGCC plants including Polk Power Unit 1 have EP ASU integration with the GT as depicted in both Figures 1 and 2. The BFD shows an elevated-pressure (EP) air separation unit (ASU) integrated to the gas turbine (GT) operation by extracting some of the GT air compressor discharge as feed to reduce the ASU air compressor size and power consumption. Figure 1: Tampa Electric IGCC Process Flowįigure 2 shows a simplified block flow diagram (BFD) illustrating the major process sub-systems included in a typical IGCC plant.

This unit is quite representative of IGCC plants in general further information is provided on the dedicated page for the Tampa Electric IGCC project.
